GLUING APPARATUS.

To all whom it may concern:

Be it known that I, PERRY H. RUE, a citizen of the United States ofAmerica, and resident of Franklin, lVarren county, State of Ohio, haveinvented certain new and useful Improvements in Gluing Apparatus, ofwhich the following isa specification.

This invent-i on relates to gluing apparatus, and particularly toapparatus for applying glue to the ends of articles, such as spokes forwheels. I

An object of this invention is to produce a gluing apparatus, which willsimplify the operation of applying glue to such articles.

A further object is to produce a gluing apparatus for wheel spokes,which simplifies the operation of applying glue to the tenons and mitersof the spokes, and which will save glue.

These and other objects I attain in an apparatus embodying the featuresherein described and illustrated.

In the drawings accompanying this application and forming a partthereof, Figure 1 is a partial side elevation and sectional view of anapparatus embodying my invention. A portion of the apparatus is shownbroken away, for convenience of illustration. Fig. 2 is a section alongthe line 22 in the direction of the arrows in Fig. 1. Fig. 8 is asideelevation of the brushes and the brush mounting frame, which formdetails of my invention. Fig. 4 is a side elevation of the frame shownin Fig. 3.

Glue is ordinarily applied to wheel spokes by hand and is a tedious andexacting operation, because the glue must be applied evenly so that itdoes not squeeze out above the miters when the spokes are inserted intothe hub. When the glue is so applied that it squeezes out above themiters, it is necessary for the finisher to remove the excess, beforeapplying the finish. Thus my invention saves time both in the gluingoperation and in the finishing process, and moreover ren ders the gluingoperation more uniform.

The apparatus includes a water or steam heated glue pot, brushes capableof moving into and being withdrawn from the pot, adjustable means forrendering the apparatus capable of being employed with wheel spokes ofdifi'erent size, and means for operating the brushes.

The apparatus illustrated is particularly adapted for applying glue towheel spokes, but I do not wish to limit my invention, as

Specification of I etters Patent.

'it may be employed in gluing other articles, such as chairrungs, orother parts of furheating vessel 7. Brushes 8 are so arranged,

that glue maybe applied to each side of the tenons and miters of a spokeat the same time. The brushes 8 are mounted on a movable frame 9, whichconsists of two end pieces 10, cross braces 11, and a bracket 12, whichis bifurcated, each prong being secured to one of the end pieces 10. Thebracket is adjustably mounted on a horizontal bar 13, and is held inplace on the bar by a clamp nut 14:. Each brush 8 is adjustably mountedon one of the side pieces 10, so that the distance between the brushescan be varied to accommodate different sizes of spokes. Each brush issecured in place in a collar 15, mounted on the end piece 10, by a clampnut 16. An adjustable stop bar 17 is mounted on the frame 9, below thebrushes 8. Each end of the bar 17 is mounted in a slot 18, formed in oneof the pieces 10, and its position in the slot is controlled by a clampnut 19, so arranged that the bar may be raised or lowered.

The inner or free end of each brush 8 is trimmed so that the outerportion will contact with the miter of the spoke, while the lowerportion is in contact with the tenon. The spoke to be glued is insertedbetween the brushes from above, and the stop bar 17 by contacting withthe end of the spoke prevents the brush from applying glue too high upon the miters, and, therefore, controls to some extent the applicationof the glue to the spoke. This bar is adjustable, so that the apparatusmay be employed with spokes having tenons and miters of diflerentlengths. The brushes 8 are shown as made of bristles, but any materialmay be employed which is suitable for applying the glue to the spokes.

The horizontal bar 13 is mounted on a frame 20, which is shown mountedon the work bench 6. The bar 13 projects through, and is held in place,in slots or ways 21, provided in the upright of the frame. Coil springs22 are mounted between the frame 20 and the bar 13, and are arranged tohold the bar in such a position, that the brushes 8 will be immersed inthe glue contained in the glue pot 5.

The bar 13 is raised, for the purpose of raising the brushes 8 out ofthe glue pot, by means of a foot lever 23, which operates the barthrough a chain and cord connection 24. The connection 24 passes througha slot 25, provided in the bar 13, and runs over a pulley 26, mounted onthe frame 20, and then is secured to the bar about midway between thesprings 22.

In the operation of gluing a spoke, the brushes 8 are raised, bydepressing the lever 23, and the end of the spoke 1s inserted downwardlybetween the brushes until it contacts with the bar 17. This operationapplies the necessary amount of glue to both sides of the tenon and bothmiters at the same time. When the spoke is withdrawn from the brushes,the lever 23 is released and the springs 22 move the brushes back intothe glue pot. One object in providing the sorings 22 is to resist theupper movement of the brushes 8, so that the operator cannot move themtoo rapidly and thus spatter glue on the outside of the glue pot.

By employing my invention, a uniform amount of glue is applied to eachspoke and is evenly distributed over the portion of the spoke to beglued. The apparatus may be so adjusted that just suflicient glue isapplied to each spoke, that no excess glue will squeeze out above themiters,when the spoke is inserted in the hub. The frame 9 011 which thebrushes 8 are mounted may be readily removed from the bar 13, merely byunclamping the bolt 1% and moving the bracket 12 along the bar. Withthis arrangement, the brushes 8 and the stop bar 17 may be readilyadjusted.

What I claim is:

1. A gluing apparatus comprising a brush frame, laterally adjustablebrushes mounted on said frame and between which the article to be gluedmay be inserted, a glue pot, and means for moving said frame into andfor withdrawing it from said glue pot.

2. A gluing apparatus comprising a glue pot, a frame movable into andout of said pot, brushes mounted on said frame and between which thearticle to be glued is adapted to be inserted, and an adjustable stopbar for determining the position of the article to be glued during thegluing operation.

3. A gluing apparatus comprising a glue pot, a frame movable into andout of said pot, brushes adjustably mounted on said frame and betweenwhich the article to be glued is adapted to be inserted, and anadustable stop bar for contacting with the article to be glued, todetermine 1ts position during the gluing operation.

l. A gluing apparatus comprising a glue pot, a frame movable into andout of said pot, brushes mounted on said frame and between which anarticle to be glued may be inserted, means for adjusting the position ofsaid brushes to vary the distance between them, and an adjustable stopfor determining the position of the article to be glued relative to thebrushes during the gluing operation.

5. A gluing apparatus comprising a glue pot, a frame movable into andout of said pot, brushes mounted on said frame, and between which thearticle to be glued may be inserted, means for adjusting said brusheslaterally to vary the distance between them, a movable bar on which saidframe is adjustably mounted, and an operating lever for actuating saidbar.
